[Implantation of formalin-preserved umbilical veins as dialysis shunts--a new method of allogenic blood vessel graft (author's transl)].

Allogenous venous umbilical implants can be used for successful vascular reconstructions and for the establishment of dialysis shunts. Presently 15 patients were treated with venous umbilical implants, in two of which a thrombosis of the implant occurred, one of them showed slight dilatation. In the case of dialysis shunts, implants serve exceptionally well. Especially the fixation in formalin can be especially recommended for preservation due to the fact that the umbilical veins can be obtained under non-sterile conditions, the immunological rejections are omitted. According to the present observations the mechanical properties are favourably influenced. At the time of the operation the umbilical veins do not possess an endothelium, nevertheless their functions are thereby affected. The results up to present time are favourable, nevertheless further investigations are necessitated.

[Reoperation in rectal cancer (author's transl)].

Carcinoma of the rectum is reported to have a local recurrence rate of 3-48 percent. In 80 percent of cases, recurrence appears within 2 years after the first operation. The possible causes of its occurrence and its localization are discussed. Early diagnosis is important. Follow-up examinations are therefore necessary every 3 months in the first 2 years. Curative secondary operations are rare. In pelvic, perineal, and genital recurrence, radiation therapy is usually considered to be the treatment of choice.

[Radiogenic carotid stenosis. The problem of radiation induced arterio-sclerosis (author's transl)].

Amongst late radiation damage, lesions of the cerebral arteries are relatively rare. The relationship between the radiation and arterio-sclerosis is discussed in connection with a 63-year old female patient with an atheromatous carotid stenosis; at the age of 5 years she received high dose rate radiation for cervical node tuberculosis. From animal experiments and an increasing number of human observations, it is concluded that radiation may be a predisposing and accelerating local factor in the formation of arterio-sclerosis. Amongst the recognised cases of radiogenic carotid stenosis or occlusion, the latent period averages 30 (9-57) years.

[Resorption of fats and carbohydrates following stomach resection and gastrectomy].

125I- and 14C-labelled triolein were used for the examination of fat absorption in patients after gastric surgery. Fat absorption decreased significantly after total and subtotal proximal gastrectomy, but less after distal gastric resection. Carbohydrate absorption, as measured by D-Xylose test, increased in the same manner after both total and partial gastrectomy.
